Description

Bisphenol A Dimethacrylate is a high-purity, difunctional methacrylate monomer widely used as a key building block in advanced polymer synthesis. This compound is valued for its ability to impart excellent hardness, chemical resistance, and thermal stability to cross-linked polymer networks. It is essential for manufacturers in the dental materials, optical lens, electronics, and specialty coatings industries seeking to enhance product performance and durability.

Application

• Dental Composites & Restorative Materials: A primary monomer for formulating high-strength, wear-resistant dental fillings, crowns, and cements.
• Optical Lens Manufacturing: Used in the production of high-index, scratch-resistant eyeglass lenses and optical adhesives.
• Electronics Encapsulation & Potting: Serves as a critical component in resins for protecting sensitive electronic components from moisture and mechanical stress.
• UV-Curable Coatings & Inks: Acts as a reactive diluent and cross-linker to create fast-curing, durable surface finishes for industrial and graphic arts applications.
• Adhesives & Sealants: Enhances the bond strength and environmental resistance of structural and industrial adhesives.
• 3D Printing Resins (SLA/DLP): A key ingredient in formulations for high-resolution, engineering-grade photopolymer resins.
• Composite Materials: Used as a matrix resin in fiber-reinforced plastics (FRP) for automotive and aerospace components.

Quality Control

Our Bisphenol A Dimethacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets precise specifications for high-performance applications. A Certificate of Analysis (COA) detailing purity, identity, and key parameters is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame.
